The second lower sleeve has a second through hole communicating with the groove. The first lower sleeve receives the first collar. The second lower sleeve receives the second collar. The L-shaped base seat has a first hollow tube receiving the first curved outer pipe, and a second hollow tube receiving the second curved outer pipe. The first curved inner pipe has a first round hole. The second curved inner pipe has a second round hole. The first positioning mount is inserted in the first curved outer pipe and blocked by the first collar. The second positioning mount is inserted in the second curved outer pipe and blocked by the second collar. The first block and the first torsion spring are inserted in the first curved inner pipe. The second block and the second torsion spring are inserted in the second curved inner pipe. The first torsion spring has a first end inserted in the first block. The second torsion spring has a second end inserted in the second block. The first block is inserted through the first round hole of the first curved inner pipe. The second block is inserted through the second round hole of the second curved inner pipe. The first lower sleeve receives the first curved outer pipe and the first collar blocks the first curved outer pipe. The second lower sleeve receives the second curved outer pipe and the second collar blocks the second curved outer pipe. The first curved inner pipe is inserted through the first through hole of the first lower sleeve, the first collar and the first positioning mount and inserted in the first curved outer pipe. The second curved inner pipe is inserted through the second through hole of the second lower sleeve, the second collar and the second positioning mount and inserted in the second curved outer pipe.

DETAILED DESCRIPTION OF THE INVENTION

[0011] Referring to FIGS. 2 to 5, a suitcase 40 has a retractable handle assembly 30. The retractable handle assembly 30 comprises a grip 33, a positioning seat 34, an L-shaped base seat 35, a first curved inner pipe 31, a second curved inner pipe 31′, a first curved outer pipe 32, a second curved outer pipe 32′, a first collar 37, a second collar 37′, a first positioning mount 36, a second positioning mount 36′, a first block 38, a second block 38′, a first torsion spring 39, and a second torsion spring 39′.

[0012] The L-shaped base seat 35 is disposed in a bottom of the suitcase 40.

[0013] The positioning seat 34 is disposed on a top portion of the suitcase 40.

[0014] The grip 33 has a first distal socket 331 receiving the first curved inner pipe 31, and a second distal socket 331′ receiving the second curved inner pipe 31′.

[0015] The positioning seat 34 has a groove 343, a first lower sleeve 341, and a second lower sleeve 341′.

[0016] The first lower sleeve 341 has a first through hole 342 communicating with the groove 343.

[0017] The second lower sleeve 341′ has a second through hole 342′ communicating with the groove 343.

[0018] The first lower sleeve 341 receives the first collar 37.

[0019] The second lower sleeve 341′ receives the second collar 37′.

[0020] The L-shaped base seat 35 has a first hollow tube 351 receiving the first curved outer pipe 32, and a second hollow tube 351′ receiving the second curved outer pipe 32′.

[0021] A first bolt P fastens the first hollow tube 351 and the first curved outer pipe 32 together.

[0022] A second bolt P′ fastens the second hollow tube 351′ and the second curved outer pipe 32′ together.

[0023] The first curved inner pipe 31 has a first round hole 311.

[0024] The second curved inner pipe 31′ has a second round hole 311′.

[0025] The first positioning mount 36 is inserted in the first curved outer pipe 32 and blocked by the first collar 37.

[0026] The second positioning mount 36′ is inserted in the second curved outer pipe 32′ and blocked by the second collar 37′.
